What causes circulating current in dual converters?

Circulating current is dual converters are caused by the out of phase voltages from both the converters. If only one converter is performing at a time, then the circulating current is not present. The circulating current is present only when both the converters are working at the same time.

How to Calculate Maximum circulating current?

Maximum circulating current calculator uses Maximum circulating current=(2*Peak input voltage*(1-(cos(Delay angle of first converter)))/(Angular frequency in radians/sec*Circulating current reactor)) to calculate the Maximum circulating current, The Maximum circulating current formula is the maximum value of the circulating current of the dual converter. Maximum circulating current and is denoted by I_r symbol.

How to calculate Maximum circulating current using this online calculator? To use this online calculator for Maximum circulating current, enter Peak input voltage (V_m), Delay angle of first converter (α₁), Angular frequency in radians/sec (w) and Circulating current reactor (L_r) and hit the calculate button. Here is how the Maximum circulating current calculation can be explained with given input values -> 0.05359 = (2*10*(1-(cos(0.5235987755982)))/(10*5)).
